HYoRoCARBofN-.BURNEa Y SPECIFICATION forming-part of Letters Patent No. 699,053, dated April. 29, 1902.

Application tiled OctoberlO, 1901. Serial No. 78,201. (No model.) I

To all whom t ntcty concern:

Beit known that I, RICHARDWITTY, a citizen of the United States, and a resident of San Bernardino, in the county of San Bernardino and State of California, have invented a new and Improved Hydrocarbon-Burner, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved hydrocarbon burner, which is simple and durable in construction, very efective when in use, and more especially designed for use in steam-boilers and the like to quickly and economically gener-n ate steam. Y

' The invention consists of novel features and parts and combinationsof the same, as will be fully described hereinafter and then pointed out in theclaims.

A practical embodiment of the invention is represented in theaccornpanying drawings, forming a part of this specification, in which similar characters of'reference indicate corresponding parts in all the views.

Figure lis a plan view of the burner proper. Fig. 2 is alongitudinal sectional elevation of the same. Fig. 3 is a reduced side elevation of the improvement'as applied to the firebox of a boiler, and Fig. 4`is a front elevation of the same with parts in section'.

The improved hydrocarbon-immer consists, essentially, of a casing A, extending in an opening B', 'arranged in the front wall of the fire-box ofthe furnace B, and lthe said ably covered with a netting or screen C for minutely dividing the mixture of air, gas,`

and steam passing from the casing through the screen into the tire-box to be burned therein, thereby heating the furnace and generating the steam. In the openA end vof. the casing A, and preferably at the bottom thereof, is arranged a detlector D for guiding the mixture of air, gas, and steam in an Aupward direction throughthe screen C and into theV fire-box.

In the closed end of the burner-casing A is arranged a transversely-extending partition A', extending from the top of the casing downward to within a short distance from the bottom of the casing, as plainly indicated in Fig.

2, the partition also reaching from side to side of the casing to form a chamber E, into which passes a mixture of air and gas, and this mixture is ejected through the nozzle E', formed at the forward end of the chamber E, between the bottom of the casing and the said partition A'. Into the top of the chamberE leads a pipe F, connected with an oil-supply pipe G and with an air-supply pipe H, the latter opening into the atmosphere and the pipe G.

connecting with an oil-supply vessel I, having a pipe I', connected with a reservoir or tank containing a large quantity of oil. In the bottom of the chamberE extends a steam.- nozzlepJ, reaching with` its outlet to Within a short distance of the outlet of the nozzle E', so that steam lpassing through the discharge end of the casing A Within the firebox, so that the burning fuel comes in contact with the pipe, and thereby superheats the steam passing through the pipe. The

V-steam-supply pipe K then extends through casing A has its inner end open and p'referthe opening B and through the oil vesselI to heat the oil contained therein and to cause thesaid'oil to quickly vaporize previous to its entrance into the Vchamber E. The pipe K after leaving the vessel Iconnects with the nozzle J, so that superheated steam passes through the nozzle J to mix with the oil and air, as previously described. A branch pipe c F' leads from the pipe F into the casing in front of the'partition A",- so that a mixture of airand gas can pass into the casing to reinforce the mixture ofgas, air, Vandy steam previous to igniting the same.

From the foregoing it is evident that when the burner is in use the steam--nthepipe K is superheated bythe burningfuel and the superheated steam is conducted through the IOO oil vessel I previous to its discharge at the nozzle J. It willbe seen that bythe arrangement described the highly-heated steam, oil, and air are not only highly heated, but are thoroughly mixed to form a very effective combustible mixture to insure a quick and economical generation of steam in the boiler.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a hydrocarbon-burner, a casing having front and rear chambers communicating with each other at the bottom, the front chamber having an open front end, an air and oil supply leading into the rear chamber at the bottom thereof, and a steam-supply leading into the rear chamber and discharging opposite the opening establishing communication between the said chambers, as set forth.

2. In a hydrocarbon-burner, a casing having the front and rear chambers communicating with each other at the bottom` the front chamberhavingan open front end, an air and oil supply leading into the rear chamber, an oil-supply vessel, and a steam-supply extending in front of the casing, thence through the oil-supply vessel and provided with a nozzle extending into the rear chamber opposite the opening establishing communication between the chambers, as set forth.

3. A hyd rocarbon-b urner,comprising a casing divided into two chambers, the front chamber having its front end open, and the rear one provided with a nozzle at its bottom, a steam-nozzle in the rear chamber opposite the first-named nozzle, an oil-supply for the rear chamber, an air-supply for the said rear chamber, a steam-supply connected with the said steam-nozzle and passing through the oilsupply for heating the oil; and means for superheating the steam in the steam-supply previous to its passage through the oil-supply vessel and previous toits entrance into the burner, as set forth.

4. Ahydrocarbon-bnrner,comprisinga casing open at one end and having a transverse partition forming an oil and air chamber in the closed end thereof, said chamber being formed with a discharge-nozzle extending toward the open end of the casing at or near the bottom thereof, and a steam-nozzle in the said oil and air chamber and having its outlet close to the said discharge-nozzle of the said chamber, as set forth.

5. Ahydrocarbon-burner,comprisingacasing open at one end, an oil and air chamber in the closed end of the said casing and formed with a discharge-nozzle extending toward the open end of the casing at or near the bottom thereof, a steam-nozzle in the said oil and air chamber and having its outlet close to the said discharge-nozzle of the said chamber, a pipe opening into the said oil and air chamber, to conduct airand gas into the chamber, and a branch pipe leading from the said firstnamed pipe, for conducting air and gas into the casing in front of the said chamber, aS set forth.

6. Ahydrocarbon-burner,comprisingacasing open at one end, and having a transverse partition forming an oil and air chamber in the closed end thereof, said chamber being formed with a discharge-nozzle extending toward the open end of the casing at or near the bottom thereof, a steam-nozzle in the said oil and air chamberl and having its outlet close to the said discharge-nozzle of the said chamber, and a deector in the open end of the casing and in advance of the said nozzles, to guide the mixture of air, gas and steam in an upward direction through the open end of the burner-casing, as set forth.

7. Ahydrocarbon-burner,comprisingacasing open at one end, an oil and air chamber in the closed end of the said casing and formed with a discharge-nozzle extending toward the open end of the casing at or near the bottom thereof, a steam-nozzle in the said oil and air chamber and having its outlet closed to the said discharge-nozzle of the said cham ber, a deflector in the open end of the casing,r and in advance of the said nozzles, to guide the mixture of air, gas and steam in an upward direction through the open end of the burnercasing, and a burner-screen extending over the open end of the said casing, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two witnesses.

RICHARD W IT'IY.
